Hey, wanna take a quick Facebook survey? It’ll be fun – we can learn what type of animal or color best represents your personality, or some other silly thing like that. All it will cost you is all the micro-specific data that has been collected about you. Oh, you’re not into those quizzes and surveys? No problem, because if any one of your Facebook friends has ever consented to one of those, there’s a possibility that connection gave somebody else access to your data anyway.
